The development of an intelligent tutoring system for helicopter flight training is described. The Intelligent Flight Trainer (IFT) is a simulator-based system designed to assist students in developing proficiency on a suite of initial entry rotary wing maneuvers. It encapsulates instructor pilot domain knowledge in an expert system shell that provides tutorial and performance monitoring functions through a synthetic voice generator. The expert system shell works in concert with a variable stability augmentation control law that makes it easier for a neophyte student to control the motion of the simulated vehicle. Experimental verification of the IFT is currently under way at the UH-1 Training Research Simulator at Fort Rucker.
